Abstract: A new and distinct cultivar of Calibrachoa plant named `Wescawhite`, characterized by its cascading and uniform growth habit; freely branching habit and short internodes; dense and bushy plant form; relatively small leaves; medium-sized flowers; and numerous white-colored flowers with violet-colored venation and circumorbital ring.
Claim: It is claimed:

1. A new and distinct cultivar of Calibrachoa plant named `Wescawhite`, as illustrated and described.
Description: Botanicaldesignation: Calibrachoa sp.

Variety denomination: `Wescawhite`.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name `Wescawhite`.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Sudlohn, Germany. The new Calibrachoa originated from a cross-pollination made by the Inventor of a proprietary selection of Calibrachoa identified ascode number 01P442, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa identified as code number 01P432, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventorin 2002 in a controlled environment in Sudlohn, Germany as a single plant within the resulting progeny from the cross-pollination.

Asexual reproduction of the new cultivar by terminal cuttings at Sudlohn, Germany since 2002, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Wescawhite have not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as temperature, light intensity and daylength without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Wescawhite`. These characteristics in combination distinguish `Wescawhite` as a new and distinct cultivar: 1. Cascading and uniformgrowth habit. 2. Freely branching habit and short internodes, dense and bushy appearance. 3. Relatively small leaves. 4. Medium-sized flowers. 5. Numerous white-colored flowers with violet-colored venation and circumorbital ring.

Plants of the cultivar Wescawhite can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed from plants of the female parent selection in thefollowing characteristics: 1. Plants of the new Calibrachoa had larger flowers than plants of the female parent selection. 2. Plants of the new Calibrachoa and the female parent selection differed in flower color as plants of the female parentselection had light blue-colored flowers.

Plants of the cultivar Wescawhite can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed from plants of the male parent selection in the followingcharacteristics: 1. Plants of the new Calibrachoa had narrower stems than plants of the male parent selection. 2. Plants of the new Calibrachoa had smaller leaves than plants of the male parent selection. 3. Plants of the new Calibrachoa and themale parent selection differed in flower color as plants of the female parent selection had light blue-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Carillon White, not patented. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed from plants of the cultivarCarillon White in the following characteristics: 1. Plants of the new Calibrachoa had lighter green-colored stems than plants of the cultivar Carillon White. 2. Plants of the new Calibrachoa had sessile leaves whereas plants of the cultivar CarillonWhite had leaves with petioles. 3. Plants of the new Calibrachoa and the cultivar Carillon White differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the top of the sheet comprises a side perspective view of typical flowering plants of `Wescawhite` grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers of `Wescawhite`.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and for the following description were grown under conditions which closely approximate commercial production conditions during the spring and summer in a glass-covered greenhouse in Sudlohn, Germany. Plants were about 20 weeks from planting rooted cuttings and grown in containers. During the production of the plants, the day temperatures ranged from 20 to 25.degree. C., night temperatures ranged from 16 to 18.degree. C. and light levels rangedfrom 3,000 to 50,000 lux.
